A tour of Bark

Integrating the Ark-protocol offers

• 🏃‍♂️ Smooth boarding: No channels to open, no on-chain setup required-create a wallet and start transacting
• 🤌 Simplified UX: Send and receive without managing channels, liquidity, or routing
• 🌐 Universal payments: Send Ark, Lightning, and on-chain payments from a single off-chain balance
• 🔌 Easier integration: Client-server architecture reduces complexity compared to P2P protocols
• 💸 Lower costs: Instant payments at a fraction of on-chain fees
• 🔒 Self-custodial: Users maintain full control of their funds at all times

This guide puts focus on how to use the Rust-API and assumes some basic familiarity with the Ark protocol. We refer to the protocol docs for an introduction.
